Alamofire 类型“ParameterEncoding"没有成员“URL"Swift 3 [英] Alamofire Type 'ParameterEncoding' has no member 'URL' Swift 3

问题描述

我正在尝试将我的代码从 swift 2 版本迁移到 swift 3 版本.我无法迁移以下代码部分，也没有找到任何解决方案.我该怎么做?

I am trying to migrate my codes from swift 2 version to swift 3 version. I could not migrate following code part and I did not find any solution for it. How can I do it?

//标记:URLRequestConvertible

// MARK: URLRequestConvertible

     public var URLRequest: NSMutableURLRequest {
            let urlComponent = NSURLComponents(string: Router.baseURL)!
            urlComponent.path = Router.basePath.stringByAppendingString(path)

            let mutableURLRequest = NSMutableURLRequest(URL: urlComponent.URL!)
            mutableURLRequest.HTTPMethod = method.rawValue

            var parameters: [String: AnyObject] = Dictionary()
            parameters["key"] = Router.key
            parameters["hl"] = "en"

            switch self {
            case .getMostPopularVideos(let pageToken):
                parameters["part"] = "snippet,contentDetails,statistics"
                parameters["chart"] = "mostPopular"
                parameters["videoCategoryId"] = TubeTrends.Settings.topTrendsCat
                if let pageToken = pageToken {
                        parameters["pageToken"] = pageToken
                }
                return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0  //This part Giving Error like Alamofire Type 'ParameterEncoding' has no member 'URL'

//            default:
//                return mutableURLRequest
            }
        }
    }

推荐答案

我将这个计算属性的名称更改为，例如，request，以避免与新的类型名称发生冲突，<代码>URLRequest.巧合的是，这个计算属性应该使用一种 URLRequest:

I'd change the name of this computed property to, say, request, to avoid clashing with the new type name, URLRequest. Coincidentally, this computed property should use a type of URLRequest:

public var request: URLRequest {
    let url = URL(string: Router.baseURL)!
        .appendingPathComponent(Router.basePath)
        .appendingPathComponent(path)

    var request = URLRequest(url: url)
    request.httpMethod = method.rawValue

    var parameters = [String: Any]()
    parameters["key"] = Router.key
    parameters["hl"] = "en"

    switch self {
    case .getMostPopularVideos(let pageToken):
        parameters["part"] = "snippet,contentDetails,statistics"
        parameters["chart"] = "mostPopular"
        parameters["videoCategoryId"] = TubeTrends.Settings.topTrendsCat
        if let pageToken = pageToken {
            parameters["pageToken"] = pageToken
        }
        return try! Alamofire.URLEncoding.default.encode(request, with: parameters)
    }
}
